Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building moulds, in particular to a ditch wall top surface line control device for pouring a drainage ditch. Background Art
[0002] In airport engineering construction, the height of the drainage ditch wall often changes due to the longitudinal slope design. Therefore, strengthening the control of the top surface line of the ditch wall is important for ensuring the flatness of the base where the cover is placed. Too high or too low a top surface line of the ditch wall is not conducive to the smooth installation of the prefabricated cover. At present, in the drainage ditch formwork project, in order to ensure that the top surface line of the ditch wall where the prefabricated cover is installed meets the design requirements, the upper edge of the template is usually controlled by the coincidence method with the design line and the hanging line method. Combined with the current existing technology, the main problems after analysis are:
[0003] 1. The upper edge of the template is implemented by coinciding with the design line. This method can effectively ensure the conformity of the top surface line with the design line with high precision, but the template needs to be cut according to the change of ditch wall height. In addition, when the design ditch wall height changes a lot and needs to be used for multiple turnover construction, the template material consumption is large and the cost is high when the drainage ditch project is large.
[0004] 2. The hanging line method is widely used in construction. However, because the control line is inside the formwork, it can only be set on one side of the formwork. In addition, the pouring process is easily contaminated by concrete, which makes it difficult for operators to observe the position of the top surface line. The control accuracy is affected, and sometimes the pouring surface is high or low, which is not conducive to the subsequent installation of the prefabricated cover. Utility Model Content
